Question: 1 / 400

Which ingredient is commonly found in hair lightening products?

Hydrogen peroxide

Hydrogen peroxide is a key ingredient commonly found in hair lightening products due to its effective bleaching properties. It works by penetrating the hair shaft and breaking down the melanin, the natural pigment that gives hair its color. This process lightens the hair, making it a popular choice for those wanting to achieve a lighter shade. Hydrogen peroxide is often combined with other ingredients to create a balanced formula that minimizes damage while still providing effective results.

While Vitamin E, activated charcoal, and jojoba oil may have their own benefits for hair care, such as moisturizing or detoxifying properties, they do not possess the bleaching capability that hydrogen peroxide provides. Therefore, they are not typically used in formulations specifically designed for lightening hair.
